A team of engineers at the University of Washington, Seattle, have designed a low-power sensor that could be placed permanently in a person’s eye to track changes in eye pressure. The sensor would be placed during cataract surgery and would detect pressure changes instantaneously, then transmit the data wirelessly using radio frequency waves, they say.

The NIH’s Bionic Man site helps viewers visually explore some of the latest bioengineering creations from research funded by the National Institute of Biomedical Imaging and Bioengineering. From prosthetics to artificial kidneys, these technologies are changing lives now and in the future.

A team of engineering researchers at the University of Arkansas, Fayetteville, say they have developed a wireless health-monitoring system that could continuously monitor an entire team of football players for physiological signs of concussion. The system includes a dry, textile-based nanosensor and accompanying network that detects early signs of traumatic brain injury by continuously monitoring various brain and neural functions.

Spinal injuries can damage the nerve supply to the bladder, meaning that people cannot tell when their bladder is full. This can create excessively high pressure on the bladder, which affects the kidneys and can lead to organ damage.

Tasked with developing intelligent prosthetic knee joints that are capable of detecting early failure before a patient suffers, a team of scientists at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland developed sensors that are integrated into the polyethylene part of the prosthesis.

A team of engineers from the University of Illinois at Urbana-Champaign and Northwestern University, Evanston, IL, have demonstrated thin, soft stick-on patches that stretch and move with the skin and incorporate commercial, off-the-shelf chip-based electronics, can support sophisticated wireless health monitoring.

Patients with cardiac diseases may ignore symptoms for months before an emergency arises. Then, seconds count. A long-term recorded electrocardiogram (ECG) may help physicians determine if an emergency is pending. A sensor belt developed at Karlsruhe Institute of Technology (KIT) for the first time allows physicians to document cardiac activity of a patient over a long period around the clock for up to six months.
